I just read this article about an up and coming meteor shower this month:

I thought it would be interesting for any who's interested and below:



Photographing meteors
The Perseids are an excellent meteor display to attempt to photograph. Meteor photography is popular. However, the chance of your recording a meteor is enhanced by using a fast lens (f 2.8 or better) and ultrafast film (ISO 400 to 1600). It makes no difference whether the camera is clock-driven or fixed on a tripod.

If your camera has an electronic shutter see if it also has a long time exposure mode that doesn't draw current. Otherwise, put in fresh batteries and plan on replacing them the next day. Mechanical shutters are preferable for long time exposures for this reason.

If all you have is a digital camera, then give it a try. Otherwise, use a film-based camera instead. The reason for this is that digital cameras suffer from thermal noise during exposures of more than a second or so.

In a dark sky, exposures of 10 to 20 minutes long can be made, but should be kept much shorter if background light threatens to fog the film. Slight moonlight, twilight or city glow can be tolerated, as they have little to do with the efficiency of a particular lens-film combination in recording bright meteors.

A successful photograph has many added values if an observer has witnessed and described the same meteor. Also, the chance of obtaining a good meteor picture can be increased by pointing the camera well away from the radiant.
